Abstract: Abstract In a feed water preheater of horizontal type with an integrated desuperheater, the last deflection chamber of the desuperheater is provided with lateral steam out-let ports (13).  As a result, the desuperheated steam does not reach the condensation zone directly as hitherto by passing into the free cross-section of the tube bundle but, instead, it passes into the free space surrounding the condensation bundle (2) on which it can then act from the outside inwards at minimum flow velocity.

Abstract: ABSTRACT OF THE DISCLOSURE Sulfur dioxides are dry scrubbed from a flue gas by introducing minute droplets containing a liquid, such as water, and an alkali or alkaline reactant, such as lime, into the spray zone in the primary spray drying chamber of a spray dryer and concurrently contacting these droplets with the hot flue gas.  The droplets are partially dried to a tacky condition before reaching a foraminous collecting member extending through the primary spray drying chamber and collect on the collecting member as a moist, porous mat.  As the flue gas continues to flow through the mat, the mat serves as a filter for removing fly ash and other particulate matter and remaining sulfur oxides react with unreacted particles of the reactant and reactive ingredients of the fly ash particles in the mat.

Abstract: A LOW POWER WIDEBAND SWITCHING ARRAY ELEMENT            Abstract A switching array comprising low power switching elements for switching high bandwidth pulse encoded signals with minimum distortion.  Each switching element comprises an emitter-coupled pair of transistors which are used to switch the pulse encoded signals.  The pair of transistors are enabled and disabled by inhibiting the flow of electrical current through the latter.  A transistorized switch controls the electrical current in the pair of transistors in response to signals from a control register within the switching array.  Since no current is flowing in the pair of transistors when the element is inhibited, the power dissipation approaches zero in the inhibit state resulting in an overall low power dissipation for the switching array since only a small number of elements are normally enabled at any time.  Each element further comprises an emitter-follower transistor for the purpose of isolating the pair of transistors from the remainder of the switching array in order to reduce the crosstalk between pulse encoded signals.

Abstract: TITLE:  METHOD AND SYSTEM FOR GENERATING SHEAR         WAVES AND COMPRESSION WAVES IN THE EARTH FOR SEISMIC SURVEYING     INVENTOR:  STEPHEN V. CHELMINSKI     ABSTRACT OF THE DISCLOSURE     A seismic source is disclosed which is particularly useful for generating horizontally polarized shear waves in the earth for seismic surveying.  It comprises an elongated, hollow, substantially vertical cylinder having an earth-contacting pad pivotally mounted to its lower end by a hori-zontal pivot shaft.   The lower surface of this large rigid pad contains multiple, blade-like teeth extending parallel with the pivot shaft for gripping the earth's surface for transmitting powerful horizontally polarized shear stress impulses into the earth.  The cylinder contains a slidable piston-like reaction mass.  The bottom of the cylinder is a strong upwardly diverging conical surface serving to focus and direct upwardly the discharge blast from each port of an air gun extending horizontally and with the axis of the air gun being oriented parallel with the pivot axis and being located a short distance above the pivot shaft.  Thus, the cylinder bottom is defined by the intersection of an elongated cylinder with a truncated cone and each air gun port is located near the center of the upwardly facing cone for focusing the blast up-wardly toward the reaction mass.  A small amount of water below the reaction piston mass and above the conical bottom surrounds the air gun ports.  The air gun is selectively dis-charged to forcibly drive the earth-contacting pad down.  By inclining the cylinder to the left of vertical or to the right of vertical while the pad seats on the earth with its parallel blade-like teeth gripping the earth's surface, the resulting sudden downward angled thrust is transmitted into the earth to generate horizontally polarized shear waves in addition to compression waves.  The entire assembly is mounted on a trans-porter from which it may be lowered against the earth's surface as desired.  The trans-porter carries a prime mover, an air compressor and receiver tank, and an air/water separator for the operation of the shear wave generator.  A seismic survey method includes pro-gressing from shot point to shot point along a seismic survey line, and at each shot point the cylinder is stood upright, is inclined to the left and is inclined to the right, in any desired sequence, and the air gun is fired with the cylinder in each of these attitudes for generating predetermined sequences and mixtures of compressional (P) waves, vertically polarized shear (SH) waves, left-handed horizontally polarized shear (SH) waves, and right-handed horizontally polarized shear (SH) waves thereby enhancing the ability to employ seismic energy transmitted into the earth from its surface for acquiring information about geological features in the earth.

Abstract: CHAIN LOGIC SCHEME FOR PROGRAMMED LOGIC ARRAY            Abstract Additional data processing capability can be added to a programmed logic array (PLA), having an AND plane and an OR plane connected serially between an input register and an output register, by inserting a multistage domino CMOS logic network between the OR plane and the output register.  The OR plane is an array of single-stage domino CMOS logic and is timed so that it  precharges simultaneously  with the multistage network.  Without prolonging the individual phase durations or adding any registers, the added domino logic network can have a propagation delay time corresponding to more than one phase of the PLA, and hence the network can have correspondingly more stages and more added data processing capability.

Abstract: -25-           51,975 ABSTRACT       A process for using an eddy current probe to precisely locate the edges of a baffle plate or support plate which surrounds a tube of a heat exchanger is disclosed herein. The process generally comprises the steps of moving the eddy current probe through the interior of the tube in the vicinity of the plate with the axis of rotation of the coil oriented parallel to the longitudinal axis of the tube. The rate of change of coil impedance is monitored as a function of the position of the coil along the longitudinal axis of the tube. When the rate of change of current flow through the coil attains its first maximum, the mid-plane of the coil is parallel to the bottom edge of the plate. This process is particularly useful in implementing maintenance procedures wherein heat exchanger tubes are selectively expanded along certain portions of their longitudinal axes in order to eliminate or reduce unwanted clearance between the tubes and the bores in the support plates through which they extend. The process may also be used to confirm whether or not a tube expansion has been performed in proper position in a tube relative to a particular support plate.

Abstract: TITLE:  AIRGUN HAVING SHAFT-BEARING-GUIDED         SHUTTLE AND CAPABLE OF FAST REPITITION SELF-FIRING         INVENTOR:  STEPHEN V. CHELMINSKI               ABSTRACT OF THE DISCLOSURE           An airgun impulsive energy source has an elongated shaft bearing surrounding the shaft of the reciprocatable shuttle for guiding the shuttle and preventing its operating or firing pistons from contacting their respective cylinder walls.  The illustrative embodiment of this airgun is propor-tioned to be self-firing with a fast repitition rate.  This airgun has an elongated cylindrical housing with discharge ports in a cylindrical wall positioned between the operating and firing chambers.  The shuttle-guiding shaft bearing is positioned in the cylindrical housing between the ports and an operating chamber.  This shaft-guiding bearing has a length which is more than 1.7 times the diameter of the shuttle shaft, while the operating and firing pistons have diameters which are slightly less than the diameter of their respective cylinder walls for eliminating contact of these pistons with their cylinder walls, thereby advantageously dramatically increasing the firing cycles which can occur before the need for replacing any worn parts.  Moreover, only the shuttle shaft guiding bearing is replaced, instead of the cylinder walls.  The housing includes internal through passages which convey high pressure gas longitudinally through the airgun so that it can be coupled to subsequent airguns connected in series with the first one.          Thus, a single source of high pressure gas may be utilized and fed in series through a sequence of airguns forming a flexible "string" of airguns capable of being inserted into and used for cleaning pipes of heat exchangers, boilers, water heaters and other internal regions of closed vessels, which are normally very difficult or impossible to reach into for cleaning.  The discharges of pressurized gas by the string of airguns in liquid, usually water, in such equipment is used to dislodge sediment and deposits from the internal surfaces of such confined regions so that the loosened foreign materials can then be flushed out by the flowing liquid.
